Since the Linux-5.3.18-lp152.60 patch (2021-01-15) I can't access CIFS shares
where the parent folder has no read permissions.

Example:
mount -t cifs \\server\users_share\alice /mnt
Alice has no permissions for the folder "users_share", so she can't see other
usernames.
But Alice has permissions for the folder "alice".

Until 5.3.18-lp152.57 such a mount worked fine.
I just got this message with 5.3.18-lp152.57:
| cannot query dirs between root and final path, enabling
CIFS_MOUNT_USE_PREFIX_PATH
But the mount was fine.

I believe this patch might be the cause for this problem:
kernel-default.15528/patches.suse.tar.bz2/cifs-ensure-correct-super-block-for-DFS-reconnect.patch:158

Note:
This is about the Linux kernel on the client.
The server is a NetApp device based on FreeBSD and Samba:

I'm currently trying to reproduce this with different servers.
